This is the catalogue raisonné of all the artist's known works, and is estimated to comprise 90 percent of his total output. The catalogue was compiled by his descendant Charles Brett, and also includes an essay on Brett's picture frames by Lynn Roberts. This study is based on the artist's own mss records, information from public and private collections, and dealer, auction and exhibition catalogues. Appendices include "John Ruskin's Review of the Val d'Aosta" and John Brett's "Commentaries" from 1886. There are notes, a bibliography and index.
